A small pink-colored shrimp takes comfortable refuge inside a well-worn sponge,
while a less noticeable but aggressively postured crab (upper left, with outstretched chelipeds)
almost seems to be moving to assault the shrimp's bunker. At left, the
brilliant crimson tentacles of a comatulid
crinoid represent the deepest red colors, complementing the more
subtle shades of the sponge and shrimp.

To give an idea of the scale of this macro
landscape, the entire image is about 2 3/4 inches (7 cm) across.
